IMPROVEMEN'I' lN ELEVATORS.

The Schedule referred to in these Letters Patent and making part of thesam-e.

To all whom it may concern:

. Be it known that I, FRANK Wiens, oi' Decatur, in the county of Maconand State ot' Illinois, have invented certain new and usefulImprovements in Hay- Elevators; and I do hereby declare the following tobe a full, clear, and exact description ofthe const-ruction andoperation of the saine, reference being had to the annexed drawingmaking a part of 1this speciiieation.

Nature and Object 'of the Invention.

In elevating hay onto a load or stack, the hay has to be elevated firstin a direct line, and, when elevated to aproper height, it is then swungaround iu a hori` zodtal line over Lthe point where it is intended to bedeposited.

In the elevators heretofore in use, while inl the actv of elevating theloaded fork, the loadedl fork takes the liuc of the hypothenuse ot atriangle, which would cause it to be thrown against the side ofthetstack. This is caused by the loaded fork being at right angles withthe line of draft, and the moment the hay is elevated from the ground,its tendency is to swing around into the line of d1a-ft,'and, indoing'so, it strikes the stack with great force.

It will be observed that this act of lifting brings the strain or powerin a twisting or curved line on the elevator, which renders the centralpost liable to be broken, and also brings an extra amount of strainonthe rope. lt also throws an extra amount of' labor on the operator ofthe fork, as he is obliged to use great effort in keeping it fromdragging against the stack, and from swinging around too suddenly 'whenraised to a plane above the' top of the stack.

To obviate these diiiieulties is the 'nature and object of thisinvention.

Figure 2 shows` the position of the horse, and the loaded fork justinthe act of being discharged on the stack. ,4

Figure 3 is a top view of the base of the machine with the ropes andtraveling pulleys attached for controlling the motion of the upperrevolving framcot the machine, and the ascending loaded fork, when themachine is made in tripod form.

C and B are cross-beams extending from one runner to the other,

The posts E, D, N, and 1t rest upon these crosspieces, of which posts, Dis the central or main standard.

The three posts E, N, and lt forni a pyramidalshaped form, and all arejoined at the apex .to a plate, S.

Through the center oithis plate passes the central post D.

To the upper end of the cent-ral post is loosely attached the trame-workT V U, forming an inverted cone, with the apex resting uponthe plate S.This frame-work readily revolve-s. l'

E, lig. 3, passing around the pulley M; thence to the base of the postN,at which point it is permanently attached.

lhe pulley M is fastened to the foot of post 1t by means ofthe nut andscrew F, and, by screwing up or unscrewing this nut, the rope J J ismade more or less tight, at pleasure; y

K K are traveling pulleys, moving along the rope J J, andl to which thepulley I, fig. 1, is attached when in use.

In fig. et this rope is attached to au elevator, when four posts areused instead of three, with nut and screw at two posts, as shown at FThere is a pulley, K, on the rope J J between each two posts of theelevator.

Gpemtion of the Machine.

The elevator is placed alongside of the place where the hay is to bcdeposited.` ."lhe horse stands o o. the side opposite the point wherethe hay lies tha-tis to be elevated onto the stack. The workman thruststhe fork into the hay; the horse then moves in a direct lin-e with theloaded fork until the hay is partially elevated, when the horse moves to,the right culetti, and

J J is a rope, fastened at one cud at base of post the pulley Ksimultaneously moves along the rope J; l l

which causes the upper part of the frame-work to revolve or turn, and bythe time the loaded fork is elevated suilicently, it is also swungaround over" the plce where it is to be deposited. Figs. 1 and 2 showthis motion. Y

In g. 1 the hay is just in the act of being elevated. In fig. 2 thehorse (in this instance) has moved to the lel't, the pulley K travelingon the rope J from near the base of the post E to the base of p'ost R,and in tuin the upper revolving part of the machine has turned with theside movement of the horse. l A

It will be observed that I am enabled, by means of -the rope J andtraveling pulleys'K K, to elevate the loaded fork and swing it aroundonto the stack simultaneously without causing any twisting or wrenchingstrain upon the frame-work; and also I relieve the workman of .the eXtraand tedious labor of keeping the ascending loaded fork from draggingagainst the side of the stack by tugging .and pullingat the guy-rope Yattached at the handle of the fork. l

In the old method the upper part of the machine.

The eross-pieee C, to which is attached the central postI D, andthe-posts N and E in the tripod form of the elevator, is made` torevolve, and, by unfastening the base of the post O, the wholesuperstructure can be lowered, as seen in rigs. 6 and 7. The pulley Ican be attached to any side of the machine, at pleasure, for the purposeof using the power on any side ol' the machine to snit the convenienceot' the'worlr,

Claims.

' \Vhat I claim as my invention, and desire to se cure by LettersPatent, is-

1. In allay-elevating mach-ine, the rope J J, in combnation'with thetraveling pulleys K K, pulley I, and rope H, constructed, arranged, andoperating in the manner und for the purpose herein described.

2. The within-described arrangement and combination of the rope J J,post-s E, D, and l, and traveling pulleys K K, for the uses and purposesherein set fort-h.'

3. In a hay-elevator, the within described means and arrangement ofropes, traveling pulleys, and fixed pulleys, for changing the directionot' the hay or weight to bc raisednnd lowered, in Vthe manner und forthe purpose herein described.
